PORTABLE WATER-HEATER.

Application filed March 19, 1918.

To aZZ whom t may concern:

Be it known that I, JOHN J. Ai-InanN, a citizen of the United States,residing at Palmer, in the county of Saratoga and State of New York,have invented certain new and useful Improvements in Portable Water-Heaters; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the saine.

This invention relates to improvements 4 in a portable water heater andhas for one of its'objects the provision of a device of this characterwhich can be disassembled and placed into a compact article so that thesame can be conveniently carriedin a. pocket and which can be assembledready to heat water of a sufficient quantity for shaving and likepurposes, thereby providing a device adaptable for tourists, soldiers,hunters, and the like.

Another object 4of this invention is the provision of a receptacleadapted to contain water and supported by a burner which heats the sameand which can be inverted and placed in the receptacle when not usingthe device providing a compact article.

A further object of this invention is the provision of means forypreventing the fuel from spilling or wasting from the burner when theburner is inverted and placed in the receptacle.

A still further object of this invention is the provision of a portablewater heater of the above stated character, which shall be simple,durable and efficient, and which may be manufactured and sold at acomparatively low cost.

With these and other objects in view as will become more apparent as thedescription proceeds, the invention consists in certain novel featuresof construction, combination, and arrangement of parts as will behereinafter more fully described and claimed.

For a complete understanding of my invention reference is to be had tothe following description and accompanying drawings, in which Figure 1is a vertical sectional view of a portable water heater constructed inaccordance with my invention.

device disassembled to provide a compact article.

Fig. 3 is a plan View of the burner, and' Fig. i is a fragmentaryvertical sectional View of the burner.

Referring in detail to the drawing, the numeral 1 indicates acylindrical receptacle having the upper edge of its wall pressed `toform screw threads 2. `A cover 3 has an annular flange 4 formed thereonwhich is pressed to form screw threads for coperation with the screwthreads of the receptacle l in securing the cover to the receptacle. Thetop wall of the cover 3 is provided with a plurality of openings 5 forthe purpose of permitting the steam from the water contained within thereceptacle to escape therefrom.

A burner 6 consists of a cylindrical bowl 7 adapted to contain alcoholor like fuel and is provided with a central opening 8 in the top wallthereof for thepurpose of permitting the bowl 7 to be filled with `thefuel and also for the reception 0f a wick 9. The wick 9 is constructedfrom cotton or other similar material wound into wick formation. Acircular collar 91 that is internally and externally screw threaded isformed upon the top wall 0f the bowl 7 about the opening 8 and hasthreaded therein a cup shaped member 10 provided with a central openingin the bottom wall thereof adapted to aline with the opening 8 in thebowl 7. A cylindrical extension 1l is formed upon the bottom wall of thecup-shaped member 10 about the opening therein and extends through theopening 8 permitting the wick to pass from the bowl 7 into thecup-shaped member 10. After the wick has passed into the cupshapedmember 10 it is flared so as to overlie the bottom wall thereof toprovide an increased burning surface to the wick. A foraminous disk 12constructed from asbestos or similar material is surrounded by a ferrule13 that is seated within an annular groove formed within the cup-shapedmember 10 so as to support the disk in spaced relation to the upper endof the wick and providing a construction wherein the fuel will be burnedthrough the disk 12 by capiliary attraction.

A cylindrical supporting member 14 is formed upon the top wall of thebowl 7 about the cylindrical member 91 and in bottom wall of thereceptacle.

spaced relation thereto and is adapted to support the receptacle 1directly over the burner and is provided with a plurality of apertures151 for the purpose of permitting the draft to the flame of the burner.

In operation, the receptacle 1 is filled or partially filled with waterand the wick is then ignited and the receptacle placed upon thecylindrical supporting member so that the Hame from the wick will playdirectly against the bottom of the receptacle so as to thoroughly andquickly heat the water therein. When desiring to carry the ,device in apocket, the receptacle 1 is reni'oved from the supporting member 111 anda cap 15 is threaded to the collar 91 so as to prevent the fuel in thebowl 7 from spilling or draining therefrom. The bowl 7 is then placedwithin the receptacle 1 in any inverted position as clearly illustratedin Fig. 2, permitting the supporting member 14 to rest upon the Thecover 3 is thenl placed upon the receptacle 1 so that the device can bereadily placed within 1 `a pocket or other convenient place.

'from the 4spirit and scope of the invention as claimed.

TWhat I claim is 1. A portable water heater comprising a bowl, anintegral supporting member on 35 Said bowl land having spaced openings,a circular collar formed on said bowl, a cupshaped member secured withinsaid circular member and in communication with the b owl, a wickextending from the bowl into 40 the cup-shaped member, and a receptaclecarried by the supporting member.

2. A portable water heater comprising a bowl, a supporting member on:said bowl, said bowl having a central opening i the 45 top wallthereof, a circular collar formed upon said bowl and surrounding saidopening, cup-shaped member threaded into said 'collar and having acentral opening in the bottom wall thereof, a cylindrical extension 50formedy upon the bottom wall of the cup and extending through theopening in the bowl, a wick eizte'ndin'g from the bowl to thecylindrical eiite'nsion into the cup, a foiramiiious 'disk carried bysaid cup and spaced 55 from the wick, a supporting member carried bysaid bowl and a receptacle carried by said supprting member;

In testimony whereof I affix my signature in presence of two witnesses.
